25 April 2000 SEESCOASEESCOA STWW - Programma UIs for Embedded Systems By Prof. Dr. Karin Coninx and Drs. Jan Van den Bergh
SEESCOASEESCOA Overview uIntroduction uApproach uUIs for Embedded Systems uInventory of UI Realization Systems uEvaluations and Results uConclusions uFuture work
SEESCOASEESCOA Introduction utask 4.1 "Evaluation of Existing UI Realization Systems" uGoals wOrientation with regard to UIs in the context of ES wOverview of existing systems wInsight in problems wPractical work as part of the evaluation uUI or GUI
SEESCOASEESCOA Approach uInformation sources: wLiterature wInternet and related media wESC Europe conference wSeminar on Windows CE by Prof. M. Timmerman wCompany visits (user group) uInventory of GUI realization tools uEvaluation through "Hands on" Experience
SEESCOASEESCOA User Interfaces for Embedded Systems uNot a lot of information in literature wProgramming techniques borrowed from mainstream UI wUsability engineering and safety issues wCurrent interest: Graphics, Java uDownscaled desktop GUI? wProgramming: OK, expertise available wDesktop metaphors not always usable! uUI in ES: who’s responsible? wDesign by product management or software developer wRealization: lack of UI expertise of developers
SEESCOASEESCOA User Interfaces for ES (continued) uProblems wDecision to use a third party API or tool wLack of tool knowledge wLimited experience with design and development of GUIs wFrequently changing definition of specs
SEESCOASEESCOA Inventory of GUI tools uTwo approaches wAdapt desktop controls and APIs wDesign controls and APIs from scratch uDifferent levels of tool support wOnly API wGUI builders (visual UI building, code generation) wPrototypers
SEESCOASEESCOA Evaluations uLocal vs. Remote interfaces uAttention points when selecting the UI systems wCover a range of UIs for ES wOO programming, C++ and Java MFC based for Windows CE (C++) Personal/Embedded Java, VisualAge MicroEdition wUI realization systems from several vendors Windows CE from Microsoft Java tools from Sun and IBM wWindows CE: promising RTOS?
SEESCOASEESCOA Evaluations (continued) uChoice of case wNot too complex, realize in different UI tools/systems wDisplay of data (output) wChange of parameters (input) wRemote interface possible uSignal generated and displayed, depending on function and parameters
SEESCOASEESCOA Evaluations (continued) uArchitectural/Conceptual model of the case
